Embodiment Construction

[0065]It should be noted that the following detailed description is directed to a method and system for producing heat energy by destroying waste and is not limited to any particular size or configuration but in fact a multitude of sizes and configurations within the general scope of the following description.

[0066]Stage 1—Waste Receiving, Sorting and RDF Production

[0067]This stage will be-described in reference to FIG. 1 and FIG. 2. Waste delivered to the plant is initially checked for oversized components [1-1]. Oversized items are extracted from the main stream and size reduced [1-2] before being returned to the main waste input stream [1-1]. The raw waste is then crushed [1-3] and moisture is extracted from the waste and after being treated is used as process and cooling water within the plant [1-4]. Sludge produced in the treatment of the moisture extracted from the waste is returned to the waste stream for destruction in a reactor (2-4). After crushing, the waste is shredded t...

Abstract

A method and system for the conversion of waste into energy in a sealed system where combustion does not take place and the operating pressure prior to the inlet of the steam or power generating equipment is maintained below atmospheric pressure. Destruction of the RDF (refuse derived fuel) is accomplished by subjecting the RDF to a high temperature environment under controlled conditions in a purpose designed and built reactor. The high temperature environment, <5000° C., is achieved through the use of one or more non-transferred plasma torches for generation of plasma gas. The plasma gas exiting the torch and provides the thermal energy for the continual gasification of metallurgic coke configured as a carbon bed in the lower part of the reactor, which acts as a thermal catalyst and this provides the thermal energy for the gasification process.

Description

FIELD OF INVENTION[0001]The present invention relates to a thermal reactor for the generation of heat energy and other recyclable by-products by the destruction of organic and inorganic waste.BACKGROUND OF INVENTION[0002]The need for efficient and environmentally sound methods of waste disposal is ever more urgent. Landfills have been used extensively for waste disposal, since landfill usage typically requires only the collection and transport of the waste to the site. However, landfills require space, and that is something many countries have less and less of, particularly in and adjacent to urban areas, which areas generate the greatest volume of waste material. Landfills, if unsecure, are also not an environmentally friendly solution.[0003]Waste organic materials may decompose and yield harmful products capable of contaminating the soil and ground water. Other organic wastes (such as vehicle tyres and plastic products) exhibit little or no decomposition in a landfill. At present,...
